TURNBUCKLE Apflicati on fi1e0 August 18, 1928. Serial No.- 300,598.

- ThiS invention rlates to turn lnnckles in general, ancl more partmularly to those designecl for use on vanous k1nds of do0rs and for other purposes. A common forma of cheap v pair 0f threaded iron 01 slaeel rocls. This is 4 inexpensive,

but the objection is, especially A when th0 device is maclaof cast or malleable iron, thatthe threads rusC, a1icl corrocle and sometimes make lt diflicult if not imposs1ble t0 tnrn the hancl bnckle when it is necessary 01' desirable 011 the other band, When the tnrn buckle proper 1s made entirely 015 brass or bronze, then the cost of production is increased ai1d the article becomes too expensive for use f01' sonne purposes.

: Generally statecl, therefore, the obje0t 01:

the invention is 130 provicle a novel and improved constrnction whereby the advantages 0f cheap 01' inexpensive construction am combi ned with freeclom 0r immunity fr0m rust and claimed and shown in the accompanying drawing in which Fig. 1 is a plan view 0f a turn buckle emboclying the principles of the ihvention, showing one endportion of the turn buckle proper 40 in longitudinal section.

Fig. 2 is an 0nd view 0f said turn bnckle,

with a porti0n thereof shown in section.

Fig. 1.

Fig. 4 is a perspectlve 0f 0110 0f the steel plates formirig the handle 01 bocly of the turn buckle prop0r.

Fig. 5 is a perspective of 0110 0f tl1e brass 01 bronze nuts provided at the encls of the turn buckle proper.

As thus illustrated,the invention comprises a pair of steel plzites 1 provicled with rigl1t angle encl portions 2 having rectangular openings 3 therein, When the plates are first formecl. The steel plzites are provided at their middles Wih the opening 4 130 permit insertion 0f a rod 01 oher instrument by Whioh to turn tl1e hand buckle.

A13 each encl 0f the tnrn buckle proper there is a brass r bronze m1thaving an outer rectangular portion 5, ancl an inner larger portion 6, the latter having .its ends curved to fit the cross Sectional curvature 'of the steel plates l, wl1en the plates and nuts are assembled together. Each nut has 011 two sides thereof the recesses 7, in two sides of the portion 5, close to the adjacent surface of the portion 6, and th0 entire nnt has a threaded bore 8 as shown. v

When the Steel plates 1 'an'd tl1e nuts are FEB-BIS, OF STERLING, ILLINOISASSIGNOR T0 FRA1\TTZ MANUIEAC-TUBIIIG CO., DIE STERLING, ILLINOIS, A CORIPORATION OF ILLI1\TOIS assembled together, the portions 5. are inserted outwar0lly through the rectangular openings 3 previously mentioned, and tl1e side portions 9 of the 'portioiis 2 are then forced inward until they are firn0ly seated. in the cu'rved recesges 7 previously mentionecl. This is shown more clearly in Figs. 2 am]. 3 0f the clrawings, fronn which it will 100 seen tl1at the portioris 9 When thus forcedinward become curved as sh0wn. In this way the brass 01' bronze nuts are anchored in the right angle end portions 2 of the Steel plates, am]. the, elements are thussolidly ancl permanently secured together.

In use, threaclecl rods 10 are held in alinement and engaged by the threaded bore 8 of the brass o1 bronze nnts, and the turn buckle proper can be rotated 0n0 Way 0r the other 130 in eflect eitl1er lengthen .01 shorten ehe connection between 13W0 points providecl by the rods 10, in the well ki1own manfner.

F01 exa1nple, these rocls can be fastened to Fig. 3 is a detail section 011 line 33 in.

plates 1 are compziratively inexpe1isive 130 manufactnre, and wl1ile the brass o1 bronze nuts are 0f m g re eXpens1ve material, the

quantipy thereof is comparatively zmall, and

' purpose.

hence the use of brass or bronze to this extent will always be freely rotali-able when necessary, even with the rods 10 made of steel. Also, ehe constrriction is light and yet strong, as compared with a turn buckle proper 001 posed of one integral piece of cast metal.

The plates l, it Wlll be seen, oan be made o-f sheet steel pressed 01 bent into the desired shape. On the other 'hand, the nuts may be cast and finished in any desired n1anner. The right angle end portions of the steel plates overlap each other, at opposite ends of the turn buckle proper, and each portion 5 extends through the said double thickness. Thus tl1e right angle, end portions 9 of the plates are very strongly anchored in the nuts '01 threaded end portins of the turn buckle proper, and the latter Will withstand considerable pull or tensile strain Without breaking or giving way under the strain, as the pull 01' tensile strain of tl1e plates 1 is straight from the corners 11 of the brass or bronze nuts. i

It will be understood, of course, that by brass or bronze is meant any for1n of commercial brass 01 bronze ordinarily employed for articles of this kind, or any other metal f equivalent character and suitable for this It Will also be understood that while it is stated that the plates 1 are.made of sheet steel, they can also be made of any other metal of equivalent character, or which may be found suitable for the purpose.

Without disclaiming anything and withont prejudice to any novelty disclosed, what I claim as 1ny invention is:

l. A turn buckle constructed t0 con1bine the advantages of inexpens:ive construction w ith freedom o1 immunity from rusting 01 corrosion of the screw threads thereof, comprising means fo-rlning the handle 01 body of the turn buckle proper, formed of metal subject to rust, and separately formed onepiece rigid end portions each provided with a threaded bore andforrned of a diflerent material adapted to prevent 0r minimize rusting o1 corrosion of the screw threads,.

auch end portion being non-removable and serv1ng to hold sa1d means n assembledrelat1on, sa1d handle or body cornpns1ng a paar 0f steel plates forrned of sheet steel bent to provide right angle end portions engaging said screw threaded end portions, the latter having means to permanently hold said plates together, and to hold said nuts in fixed position against both axial and rotary displacement in said body.

2. A turn buckle constructed to combine the advantages of inexpensive construction with freedom or immunity from rusting or corrosion of the sorew threads thereof, comprising means forming the handle or body of the turn buckle proper, formed of metal subject to rust, and separately formed onepiece rigid end portions each pro-vided with a threaded bore and formed of a different material adapted to prevent or minimize rusting 01 corrosion 0f thescrew. threads, each end portion being non-remoirable and serving t0 hold said means in assembled relat10n, sa1d handle 01 body compms1ng afpa1r of steel plates formed of sheet steel bent to provide right angle end portions engaging said screw threaded end portions, said end portions comprising nuts formed of relatively non-rusting composition metal, euch nut having a reduced 0Uter portionof olygonal formation, and th'e bent end port1on-o-f each steel plate having an opening of' similzlr shcpe t0 receive said reduced portions, the latterhaving means to permanently hold said plates together, and t0 hold said nuts in fixed position against both axial and rotary displacement in said body.

3. A turn buckle constructed to combine tl1e advantages of inexpensive -constructin with freedom 01' immunity frorn rusting or corrosion of the screw threads thereof, comprising means forming the handle or body of the turn buckle Proper, formed of metal subject to rust, and separately formed"onepiece rigid end portions each provided With a threaded bore and formed of a diflerent material adapted to prevent or' minimize ru'sting or corrosion of the screw threads, e'ach end portion beingnon-removable and serving to holdsaid means in assembled relation', said handle or body comprising a pair of .steel plates formed 0f sheet steel bentto provide right angle end portions engaging said sbrew threaded end. portions, rach pla te being curved .to give the handle a more or les s cylindrical shape, said end portions compnsing nuts formed of relativelynon-rusting com osition metal, each mit. having a red'uced outer portion of polygonal formation, and the bent end portion of each steel plate having an openingof similar sha e toreceive said reduced portions, each re uced portion having recesses into Which portions of the steel 'plate end portions are forced to solidly and permanently anchor the said non-rustihg co1nposition nuts in the .said bent end"por= tions 013 the steel plates, and the inside Portions of said nuts being cnrvedtofit said plates 1nade of sheet metal bent into shape to provide right angle end. portions hawing openings therein, and threaded one-piece nut portions anchored in said openings, each one-piece nut having means to permanently hold said plates together in fixed relation, said means comprisin lateral recesses inthe nut portions into wT1ich portions of said plates are forced.
